Normally it would be crystalline or a solid powder like substance soluble in water. Change would be based on conditions you impose.
You must state the purpose of using MgSO4.
MgSO4 is soluble in water, which is in aqueous state (aq) or can be written as MgSP4(aq).
The standard state of magnesium is solid.
It is in solid state.It is a metal.Answer:Pure magnesium is not found in nature as it is reactive with many substances. Commercial sources (ores and minerals) include carnallite, dolomite, brucite, magnesite, ovaline and talc.Magnesium also also exists as a soluble chloride salt in seawater, solution mined salt and other (NaCl) salt sources.
Magnesium oxide is a solid.
You must state the purpose of using MgSO4.
No zinc does not react with magnesium sulphate it comes on 6th no. On the activity series of metal's list whereas magnesium is on the 4th no. So it doesn't
A chemical change involves a rearrangement of atoms to form new substances with different chemical structures. In contrast, a physical change involves a change in the state, shape, or form of a substance without altering its chemical composition.
Magnesium forms cations with a charge of +2, and oxygen in oxyacids is assigned a formal charge or oxidation state of -2. There are four oxygen atoms in each sulfate ion, so that the total charge from oxygen is -8. This means that the oxidation number of sulfur must be +6, so that the total charges will sum to zero, as required for a compound.
I will assume you mean lead with a 2 oxidation state. MgSO4 + Pb(NO3)2 >> Mg(NO3)2 + PbSO4
Grinding copper sulfate pentahydrate is a physical change because no new substances are formed during the process. The copper sulfate remains the same chemical compound, but its physical state is altered as it is broken down into smaller particles.

Because you change the composition of the original matter. It is no longer in its original state. Chemical Change- Change in composition; burning, crushing, etc. physical change- changing state, but substance's composition stays same; freezing, boiling, etc
Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.
Molten magnesium is still metallic magnesium. It is in liquid state.
